Primary intra-fourth ventricular meningioma: Report two cases

Abstract

Meningioma's occurring intraventricular region are rare and these occurring in the fourth ventricle is even rare. Because of the rarity, it is not usually considered as a differential diagnosis in any age group. Clinical features and Imaging is not characteristic, and most of them are thought to be some different tumor. Here, we discuss two cases harboring a primary fourth ventricular meningioma Grade II, which was surgically excised successfully. Total excision was achieved in both cases and as the tumor was firm to soft and vermian splitting was not required. Understanding the clinical features and a careful preoperative radiological examination is required to differentiate this tumor from more commonly occurring lesions at this location.
